項に記載の燃料コツクの自動閉弁機構。[Claims for Utility Model Registration] (1) A fuel tank that can open and close a fuel passage for supplying fuel to an engine, and a fuel tank that can be driven only in the closing direction as the temperature of the engine decreases. An automatic valve-closing mechanism for a fuel pot, characterized by having a temperature-sensitive actuator connected to the pot. (2) The temperature-sensitive actuator engages with a shape memory alloy member that reversibly deforms in response to a temperature change passing a predetermined temperature in a direction in which the fuel pot is closed, and the direction in which the fuel pot is opened is An automatic valve closing mechanism for a fuel tank according to claim 1, characterized in that it has a ratchet means that is brought into a free state. (3) The temperature-sensitive actuator is a diaphragm actuator that defines an air chamber, and only discharges air from the air chamber when the temperature is above a predetermined temperature, and when the temperature is below the predetermined temperature. Utility model registration claim 1 characterized by having a check valve means capable of both suction and discharge.
Automatic valve-closing mechanism for the fuel tank described in .
